Folks,
After I hold buttons down I keep getting to into warning screen for custom os and when I push the volume up button to go to download screen it just goes blank/black but power is still on. FYI, USB debugging is checked. Any suggestions?
Does Odin sees it?

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.
I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?
After flashing CM 14.1 my tablet shows the LG logo and that it can't verify data etc. Then I see a blue screen for like one second and screens goes dark - black.
Can't enter recovery or download (download because the tablet has to be turned off) and I don't know how to turn it off, If I'm not in android.
Any help?
Even though the tablet won't turn off you should able to get it into recovery or download mode.
I just hold down the power and volume down and it should reboot and once you see the LG logo try releasing the power button (keep pressing the volume down) then quickly press and hold the power button again. Does the get you into recovery?
Hello,
Can someone give me the EXACT procedure to enter into Download and Recovery mode please?
If my tab (SM-T830) is switched off, and I switch it on by pressing Vol down + Power and I keep pressing both buttons, it will boot until the first splash screen (Samsung Galaxy Tab S4 Powered by Android) then after this screen, it will reboot..
If I release buttons during this splash screen, it boots up normally
I already succeeded to enter to download or recovery modes before but I have no idea how. I guess I must release 1 or 2 button at the point but when ?
Thanks
Hello,
Hopefully this will be helpful, the following procedure worked for me:
make sure the tab is off
plug the USB cable in your tab (but not in your computer)
hold down both volume buttons together
plug the USB cable in your computer
then the tab start (you may release the buttons) with a menu allowing you to choose (Vol +/-) between download mode and reboot.

It works perfectly, thank! That's a weird way to go to DL mode but it works!
And once I'm already in DL (and flashed a tar with Odin), do you know how I can restart directly to Recovery mode without rebooting to system?

This is really late, but go to recovery and select download mode.
Power off
Hold down all three buttons (power, vol down, vol up)
Once it vibrates let go of power and vol down, continue to hold vol up. Never fails.

Did this several times exactly the same way it's described and it fails every single time. Other way worked perfectly and easily on my first try.
So I have spent hours now looking around for an answer the phone is find my phone locked and I can't remember my pin code. I have done all the tricks with the combination keys.
The usual way to get into Recovery mode is Hold V+ and power until the phone vibrates and you should be in recovery mode release the keys. (Doesn't work)
Iv read that you should have the USB cable connected from pc/laptop while you do the same holding V+ and power button... (doesn't work ether)
and download mode should be very easy just hold V+ and V- plug USB cable from pc/laptop and you should get into download mode by pressing V+. Will only show charging Icon and that's its.
So is it possible to turn off this modes from the manufactor? Or is this a completely new security future? How can you use odin? How can you wipe the cache? If you end up having some issues.
Im going nuts....
No way to get into fastboot ether. So if anyone know why this is happening to me or got any solution I would appreciate it.
Plug in your cable with the phone turned on. Hit Power Off and wait for the phone to fully turn off. The charging logo will show up so let the animation do its thing. After maybe 20 seconds, press Volume up + Power and keep them pressed until you boot to recovery. If the command wasn't recorded in the first place and the phone is still off after more than 15 seconds, let go of the buttons and press them again and keep them pressed until it boots in Recovery

It will not work. How the hell should I be able to cle3ar cache if I got a boot loop ??? They can't just turn off recovery mode mand download mode??? This is so strange even paying for a frp reset but not even he does know what wrong??? Can they turn off fastboot, recovery mode and Download mode on this new phones? Is it because its locked with find my phone? 1 week researching now. It will only vibrate. And my PC cant find my phone anymore worked fine 30min ago nothing has changed... So annoying never seen this happened before every combination with buttons to get in any mode doesn't work only vibrates and go to pin lock screen...
Take it to a Samsung Experience center at best buy. Or send it into Samsung for repair.
download mode:
Turn off phone
plug cable in pc but not in phone
pres "volume +" and "volume -" in the same time
plug cable in phone
recovery mode:
plug cable in pc and s22
power off
press "volume +" and power
wait until see recovery mode

thats a solid advice assuming his bootloader/recovery/download mode is fully functional then this advice works, in his case and in mine too it does not work and trying to get to the root of the problem is the key. In my case recovery mode gives error on screen so it may have to do with the way firmware is installed as these modes are not accessible.
have you sorted it out? Its nearly a year onwards =)

This, at index 2:48 minutes.
It needs to be connected to the PC. Another screwy quirk Samsung added recently. Your button timing/sequence matters as well.
On my N10+'s you can go into recovery directly with a restart if you do it right. Otherwise they will puke on you.
When I was going to root my phone, I must have taken a wrong choice on the download screen (I can't remember what) because it got to another screen like the attached screenshot over this text: "Press power key to continue", but pressing that key does nothing. Every time I start the phone, that screen comes up for about 10 seconds, and then it boots in an apparent normal way.
The same screen of the screenshot keeps coming back when I press the keys for download mode (Volume Up + Volume Down + Power). Pressing the keys for recovery mode (Volume Up + Power, from off) nothing changes. However, I pressed that keys for over 2 minutes and the phone entered in recovery mode. Then, I could wipe everything and rebooted, but the problem persisted exactly as before.
I can't get to the download mode, so I can't download any ROM. What can I do?
Just confirming, you've plugged in the usb cable before pressing the buttons to go to download mode?
Might also try using ADB commands to get to bootloader...
